DESCRIPTION
Output status control pin. Connects to a PNP-type voltage parator.
Connects to the DC motor. Diodes for absorbing counter electromotive force are contained on the V CC and GND sides. Grounded
Connects to the DC motor together with pin 3 and has the same function as pin 3. This pin is controlled by the inputs from pins 1 and 2.
Power supply pin. This pin has a function to turn off the output when the applied voltage exceeds 30V, thus protecting the IC and the load.
Power supply pin for the control section. This pin is pletely separated from the VCC pin.
